Purpose

Scope: Architecture Tools

Scope Modeling and Repository Tools Criteria Working Sub-Group responsible for setting: Tool assessment criteria Tool assessment approach Tool criteria and approach cover Modeling tools for producing architecture work products, and Repository tools that store architecture elements and work products

EA Documentation Environment

Definition — Enterprise Architecture (EA)* An EA is an explicit description and documentation of current and desired relationships among business and management processes and information technology

Definition — Enterprise Architecture (EA)* The EA will define Principles and goals and Set direction on promotion of interoperability, open systems, public access, compliance with GPEA, end user satisfaction, and IT security

Definition — General Uses of an Enterprise Architecture (EA)* and an EA Tool Set An Enterprise Architecture: Is the basis for decision making and planning Governs the identification, selection, and development of standards Is the mechanism for managing change within the enterprise Enables effective communication about the enterprise Therefore, an EA tool set must help: Organize, integrate, and roll-up architecture information Identify standards and associate them with architecture information Include capabilities for configuration and change management Serve as a centralized repository to effect communication

Definition — Federal Enterprise Architecture (FEA)* FEA [is] a business-based framework for Government-wide improvement The FEA is being constructed through a collection of interrelated "reference models" designed to facilitate cross-agency analysis and the identification of duplicative investments, gaps, and opportunities for collaboration within and across Federal Agencies. These models are defined as: Business Reference Model (BRM) Performance Reference Model (PRM) Data and Information Reference Model (DRM) Application Capability Reference Model (ARM) Technical Reference Model (TRM)

Definition — General Uses of a Federal Enterprise Architecture* and a FEA Tool Set The FEA is being constructed to facilitate: Cross-agency analysis Identification of duplicative investments and gaps Identification of opportunities for collaboration within and across federal agencies Therefore a FEA tool set must help: Organize, integrate, and roll-up architecture information across-agencies Identify IT systems and standards and associate them with architecture information Include capabilities for configuration and change management Serve as a centralized repository to effect communication

Uses of a FEA Tool Set Facilitate identifying, organizing, and disseminating The enterprise vision The business processes and business functions Facilitate integrating architecture development within the enterprise Facilitate collaboration, information sharing, and information reuse Provide decision makers with better, more consistent information and tools Facilitate linking important program milestones and resource decisions to architecture activities

Tool Users Categories Architecture Designers and Developers: Require direct support through modeling, modeling standards, and customization capabilities Enterprise Architects: Need to maintain, update, and oversee the architectural elements and work products across the enterprise Planners, Stakeholders, and Management: Need to run analysis, obtain guidance, and evaluate baseline and current models Browsers: Need specific views and perspectives of the architecture via technologies such as the web

Tool Users Characteristics May be in several locations Have a variety of platforms Require numerous mechanisms to access the information from viewing relatively static information on web pages to interactive access to components and relationships
